I've got 200 more songs to go. but have messed around with it for a bit. It's pretty f'ing good. Very seemless. There is a setting where as soon as you put music on your computer, it automatically syncs to the cloud and your other devices. SO after a couple minutes of you downloading or ripping some tunes, they are on your phone too. The streaming playback sounds really good, even over 3G. Pretty darn quick too.
